  Site-wide configurations and start of the ImageAnnotator gagdet. Split into a
  separate file for three reasons:
  1. It separates the configuration from the core code, while still
  2. making it impossible for someone else (e.g. a malicious user) to override these
     defaults, and
  3. makes configuration changes available quickly: clients cache this file for four hours.
